摘要
为了研究胶原蛋白肽补血微囊工艺条件以及包合前后理化性质及结构变化,采用阿拉伯胶和明胶对黄芪甲苷、阿魏酸和鱼胶原蛋白肽进行包合,采用热重分析、傅里叶红外光谱和X射线衍射对包合后产物的理化性质和结构特性进行检测。结果显示,采用Box-Behnken响应面试验对包合工艺进行优化,得到最佳包合工艺条件为芯壁比1:8.333、壁材浓度0.91%、超声时间15.94 min,得到平均包合率75.35%;修正为:芯壁比1:8、壁材浓度0.9%、超声时间16 min,得到黄芪甲苷包合率73.59%、阿魏酸包合率88.76%、鱼胶原蛋白肽包合率65.80%,包合工艺的平均包合率76.05%。X-射线衍射(XRD)、热重分析(TG)、傅里叶红外光谱(FI-TR)表明包合物已经形成,而且包合物显著增加芯材稳定性。
In order to study the preparation conditions of collagen peptide microcapsules for replenishing blood and the change of physicochemical properties and structural before and after inclusion.This study used acacia and gelatin to encapsulate the astragaloside,ferulic acid and fish collagen peptides.The physicochemical properties and structural properties of the encapsulated product were examined by thermogravimetric analysis,Fourier transform infrared spectroscopy and X-ray diffraction.The results showed that the inclusion process was optimized by Box-Behnken response surface test.The optimal inclusion process conditions were as follows:core wall ratio,1:8.333,wall material concentration 0.91%,ultrasonic time 15.94 min,and average inclusion rate 75.35%.The correction was as follows:core wall ratio 1:8;wall material concentration 0.9%,ultrasonic time 16 min,inclusion rate of astragaloside IV,ferulic acid and fish collagen peptide,were 73.59%,88.76% and 65.80%,respectively.And the yielding the average inclusion rate was 76.05%.X-ray diffraction (XRD),thermogravimetric analysis (TG),and Fourier transform infrared spectroscopy (FI-TR) indicated that the clathrate had formed and the stability of the core material was significantly improved after inclusion.
